We are launching the World Catalogue of this important subfamily of Curculionidae. The work provides keys to all genera, lists of species and synonyms, systematic combinations, and is authored by an eminent authority on the group. The work considers 1316 valid species, 167 genera and 11 tribes. A new tribe and 16 new genera are described. Other important features of this work include four new placements, 88 changed combinations, 45 new synonyms, eight changes of rank and eight revisions of status. Each species is provided with details of geographical distribution and habitat where known.

The scale of the systematic revisions and new findings make this an outstanding contribution to the literature dealing with Curculionidae. There is an extensive bibliography and composed indexes to valid and invalid taxa (about 4,600 entries).
